注意：从Vue Router的2022-8-22 更新后，我们使用param传参在新页面无法获取数据。可以有其他解决办法：

1、使用query方式传参

注意query传参只能用路由表中的path，不是name，并且所有参数都会显示在URL地址上。

2、使用 History API 方式传递和接收

在跳转前的页面使用 state 参数，获取通过history.state.参数名

代码示例

Home页面

<template>
    <h1>Home</h1> 
    <el-button @click="EditHandle" type="primary" :icon="Edit" circle />
    <el-button @click="CheckHandle" type="success" :icon="Check" circle />
    <br>
    {{ msg }}
</template>
<script lang="ts" setup>
import {Check,Edit} from '@element-plus/icons-vue'
import {ref,onMounted} from 'vue'
import { useRouter,useRoute } from 'vue-router'
let router = useRouter()  //等同于vue2中的this.$router
const route = useRoute()
const EditHandle = () =>{
    window.open('http://127.0.0.1:5173/about','_blank')
}
const CheckHandle = () =>{
    router.push({ path: '/about', query: { plan: 'private' } })
}
let msg = ref()
onMounted(() => {
    msg.value = history.state.name
    
})
</script>

About页面

<template>
    About-------{{ msg }}
    <br>
    <el-button @click="MessageHandle" type="info" :icon="Message" circle />
    <router-link to="/">
        <el-button @click="StarHandle" type="warning" :icon="Star" circle />
    </router-link>
</template>
<script lang="ts" setup>
import {Message,Star} from '@element-plus/icons-vue'

import {ref,onMounted} from 'vue'
import { useRoute, useRouter } from 'vue-router';
 
//2:定义变量
const route = useRoute();
const router = useRouter()
let msg = ref()
onMounted(() => {
    msg.value = route.query.plan
})
const MessageHandle = () =>{
    router.push({name:'home',state:{name:'张三'}})
}
const StarHandle = () =>{
    
}
</script>
